[問題] 想問有關BaseAdapter的問題...

[easterday (....)]

大家都知道如果要實作BaseAdapter的實作品都要改寫getView函式;
可是我用起來就一直覺得很奇怪
因為我習慣用LinearLayout來排版
所以寫起來就會像這樣...
public class MyBaseAdapter2 extends BaseAdapter{

Activity activity;
ArrayList< ArrayList<String> > Data;

public View getView(int position,View convertView,ViewGroup parent) {
   LinearLayout Line=new LinearLayout(activity);
   Line.setOrientation(LinearLayout.HORIZONTAL);
   int sz= Data.get(0).size();
   TextView[] LineElement=new TextView[sz];
   for (int i=0; i< sz; i++)
   {
     LineElement[i]=new TextView(activity);
     LineElement[i].setText( Data.get(position).get(i));
     Line.addView(LineElement[i]);
   }
   return Line;

}
}
上面那種寫法跑起來可以跑
但是我想包在自己的class內處理
例如
public class MyStringModel {
        Activity activity;
        ArrayList<String> Data;
        public LinearLayout Response;
        MyStringModel(ArrayList<String> inn,Activity a) {
                Data=inn; activity=a;
                constructResponse();
        }
        private void constructResponse() {
           Response=new LinearLayout(activity);
           Response.setOrientation(LinearLayout.HORIZONTAL);
           int sz= Data.get(0).size();
           TextView[] LineElement=new TextView[sz];
           for (int i=0; i<sz; i++) {
              LineElement[i]=new TextView(activity);
              LineElement.setText( Data.get(i));
              Response.addView(LineElement[i]);
           }
        }
}
這樣的話BaseAdapter2就可以這樣寫
public class BaseAdapter2 extends BaseAdapter {
        MyStringModel[] M;
        public BaseAdapter2(ArrayList< ArrayList<String> > data,Activity a) {
            ...
            M=new MyStringModel[sz];
            for (int i=0; i<sz; i++) {
               M[i]=new MyStringModel(data.get(i),activity);
            }
            ...
        }
        public View getView(int position,View convertView,ViwGroup parent) {
            return M[position].Response;
        }
}
可是怎麼試都會當機....
有人能幫我看看嗎?

推 givemepass: Log?
推 TJLduck: 你這程式編譯會過嗎？
→ TJLduck: LineElement.setText( Data.get(i));
→ samsumg: 樓上這行編譯可過 因為ArrayList<String>
推 TJLduck: LineElement[i].setText( Data.get(i)); 不是這樣才會過
→ easterday: 最後檢查Log發現,如果把Horizontal和LayoutParam拿掉
→ easterday: 就不會當機了,但是這樣很醜...
